No. 599,555. Patented Feb. 22, 1898.

CLARENCE P. FLORA, OF MADISON, INDIANA, ASSIGNOR OF ONE-HALF TO WVILLIAM H. BRUNING, OF NEW YORK, N. Y.

SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 599,555, dated February 22, 1898.

Application filed August 14,1897. Serial No. 648,256. (No model.)

To all whom it may concern.-

Be it known that I, CLARENCE P. FLORA,

residing at Madison, Jefferson county, Indiana, have invented a Ventilator-Sash Lock, of which the following is a specification.

My invention relates to window-sashes; and its. object is to form a lock for the sashes both in a closed position or in an open position for ventilating purposes. For such latter pur pose I provide means for locking either or both sashes in open position to regulated degrees.

In the accompanying drawings, Figure l is a side sectional elevation of a window-casing, showing the upper sash lowered or open and locked by my device Fig. 2, a similar View showing both sashes open and locked; Fig. 3, an enlarged view in perspective of the lock device; Fig. 4:, a detail view of a portion of one of the side rails of the upper sash; and

Fig. 5, a top plan View of a portion of the lower sash, showing the lock deviceout of position. 1

The window-casing 1 is provided with the usual lower and upper sashes 2 and 3, respectively. Upon the top rail of the lower sash and near one side I secure my lock device, which comprises, preferably, a base-plate 4, which may be fastened to the sash by screws 5 and 6 or by any other desired means. Upon this base-plate is pivoted a plate 7, which is preferably rolled up at one side to form a cylinder or bearing-sleeve 8 for a plunger-rod 9.

It is obvious that the base-plate may be dispensed with and the plate 7 pivoted directly to the sash, although the way shown will be found preferable. Integral with this rod or secured thereto is a member or end piece comprising a.handle or finger portion 10 and a curved hook portion 11. A spring 12 is coiled around the rod andabuts at its end against the end piece and the cylinder 8, so that the rod is normally retracted away from the upper sash. The rod is preferably provided with a pin or stud 13, adapted to slide in a slot 14 in the cylinder 8, in order to prevent rotationof the rod except when thrust forward against the tension of the spring.

Upon the side of the window-casing I arrange two screws or pins 15 and 16' for a purpose fully understood when the operation is described. The pin 15 is arranged at such a height as to be engaged by the hook 11 when the lower sash is closed, and the pin 16 is arranged at a proper and predetermined height above the other pin. More than two pins may be used, but this numberwill in practice be found sufficient.

One of the side rails of the upper sash has a series of holes 17, 18, and 19. They may be of any desired number and distance apart and are adapted to accommodate the forward end of the plunger-rod.

' The screw 6 is preferably somewhat raised, or has an enlarged head to form a stop, as shown in Fig. 5, to prevent the plate 7 from rotating too far. Any other form of stop may be used, such as a portion of the base-plate itself raised or turned up to interfere with the plate 7 when turned.

When it is desired to use my device'to lock the sashes closed, the plate 7 is turned to bring the plunger at right angles to the sash. The plunger is thrust inward into the hole 17 and thence turned a quarter, whereupon the hook portion 11 will engage the lower pin 15 and retain the rod in the hole. The sashes are now locked together.

WVhen the device is used to provide for ventilation by means of theupper sash, such sash is lowered until the hole 18 or 19, according to the degree of opening desired, is opposite the plunger-rod, which is operated as before, except that the rod enters a higher hole in the sash. The open upper sash is now locked to the closed lower sash, as shown in Fig. 1. It

is apparent that in like manner the lower sash alone may be locked in raised or open position, so that all the ventilation is obtained from below, the upper sash remaining closed.

As illustrated in Fig. 2, my device may be used to lock both sashes open, so as to have ventilation at both top and bottom. In this case the upper sash is lowered as before and the lower sash is raised until the plunger-rod will register with one of the upper holes, say hole 19, although it is understood that holes above the one marked 19 may be employed. The lock is then manipulated as before and the hook will engage the upper pin 16.

Although I have described more or less prenot intend to be understood as limiting myself thereto, as I contemplate changes in form, proportion of parts, and the substitution of equivalents as circumstances may suggest or render expedient.

I claim- 1. The combination ofa window-easing, upper and lower sashes therein, the upper sash having a series of holes in one of its side rails, a pin upon the casing, a normally spring-retracted plunger pivotally mounted upon the lower sash, the forward end of the plunger being adapted to be thrust in one of said holes and the other end behind the pivotal point having a catch device adapted to engage said pin and keep the plunger thrust forward against the tension of its retracting-spring.

2. The combination of a window-easing, upper and lower sashes therein, one of the side rails of the upper sash havinga series of holes, a pin upon the casing, a bearingplate pivoted upon the top rail of the lower sash, a norm allyretracted rod mounted upon the bearingplate, the forward end of such rod adapted to enter one of said holes and the other end thereof adapted to engage said pin and not only to lock the lower sash to the casing, but also to positively hold the rod forward to lock both sashes together.

The combination of a window casing, upper and lower sashes therein, the upper sash having a series of holes in one of its side rails, a pin upon the casing, a spring-pressed plunger located upon the sash and adapted to be received by said holes and a hook connected to the plunger and engaging said pin whereby the hook holds the rod protracted and also looks the sashes against vertical movement,

4. The combination of a window-easing, upper and lower sashes therein, one side rail of the upper sash being provided with a vertical series of holes, a plunger-rod adapted to enter the holes, a plate pivoted to the lower sash and having a bearing for the rod, a spring normally retracting the rod and keeping it from the holes, and means on the casing for engaging the rod and holding it forward into one of the holes against the tension of the spring when it is desired to lock the sashes to ether and to the casing.

o. The combination of awindow-casing, upper and lower sashes therein, one side rail of the upper sash being provided with a vertical series of holes, pins arranged above each other upon the side of the casing, a spring-retracted plunger-rod pivoted to the lower sash and adapted to enter the holes, and a catch device located upon one end of the rod and adapted to engage the lowermost pin when the sashes are both closed or the upper sash alone is open and to engage the pin or pins above such low ermost pin when both sashes are open or the lower sash alone is open.

6. The combination ofa window-casing, upper and lower sashes therein, one of the side rails of the upper sash having a vertical series of holes, two or more pins in vertical line upon the casing, a plunger-rod adapted to enter the holes, a plate pivoted upon the lower sash and having a bearing for the rod, a spring normally retracting the rod away from the holes, and a handle and catch device upon one end of the rod, such catch device engaging one of the pins when the rod is forced into one of the holes by the handle and holding such rod therein against the tension of the spring.

7. The combination of a casin g 1, lower sash 2 and upper sash 3, the upper sash having a series of holes 17, 18 and 19, a base-plate 4' upon the lower sash, a plate 7 pivoted to the base-plate and having a bearing-sleeve 8, provided with a slot 14, a plunger-rod 9, a catch device 11 to engage the pins, a spring 12 around the rod, a pin 13 upon the rod and normally in position in slot 14, and astop device 6 for limiting the movement of the plate 7.
